Eric Fiselier 70ebeabfb8 Rewrite cxa guard implementation. ... This patch does three main things: (1) It re-writes the cxa guard implementation to make it testable. (2) Adds support for recursive init detection on non-apple platforms. (3) It adds a futex based implementation. The futex based implementation locks and notifies on a per-object basis, unlike the current implementation which uses a global lock for all objects. Once this patch settles I'll turn it on by default when supported. llvm-svn: 359060		2019-04-24 01:47:30 +00:00
